Meta AnalysisPooled assessment of computed tomography interpretation by vascular neurologists in the STRokE DOC telestroke network.
The objective of this pooled analysis was to determine the level of agreement between central read and each of 2 groups (spoke radiologists and hub vascular neurologists) in interpreting head computed tomography (CT) scans of stroke patients presenting to telestroke network hospitals. ⋯ Both vascular neurologists and reports from spoke radiologists had excellent reliability in identifying radiologic rt-PA contraindications. These pooled findings demonstrate that telestroke evaluation of head CT scans for acute rt-PA assessments is reliable.

Case ReportsCerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy without anterior temporal pole involvement: a case report.
The location of white matter lesions, especially in the anterior temporal poles (ATP), is helpful in the diagnosis of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). We report a 49-year-old man with CADASIL who developed migraine with atypical aura, silent lacunar infarcts, and leukoencephalopathy without involvement of the ATP. ⋯ Particularly in patients with CADASIL, the aura is often atypical (hemiplegic, basilar, or prolonged). A diagnosis of CADASIL should be considered in patients with lacunar infarcts, leukoencephalopathy, and migraine with atypical aura, even in the absence of white matter lesion in the ATPs.

The time from symptom onset to seeking medical assistance (decision delay) accounts for a proportion of prehospital delay in acute stroke. The aims of this study were to identify factors related to decision delay and calling the emergency medical services (EMS) as the first medical contact. ⋯ The decision to seek medical assistance in acute stroke accounts for more than half of the prehospital delay. Severity of symptoms and living together are related to an early decision (≤1 hour). Previous stroke knowledge does not affect decision delay or EMS use.

Geometry of saccular cerebral aneurysms not associated with a branch vessel.
Saccular cerebral aneurysms located at nonbranching sites are uncommon. Their distribution, morphological features, and presence of a branch vessel or a tiny perforator(s) separate from the aneurysm neck were investigated. ⋯ Saccular aneurysms occurring at nonbranching sites are uncommon. Their geometry is particularly favorable for flow directed stents and is most amenable to aneurysms located on large-diameter conducting vessels such as the internal carotid, vertebral, and vertebrobasilar vessels. Smaller parent arteries harboring this type of aneurysm will require new technology to maintain patency of these more distal vessels. If endovascular techniques cannot achieve aneurysm sac obliteration, then open craniotomy and aneurysm clipping will provide a satisfactory alternative.

Favorable functional recovery in overweight ischemic stroke survivors: findings from the China National Stroke Registry.
Obesity paradox has been reported because of the inverse relationship between the body mass index (BMI) and mortality in stroke patients. The relationship between BMI and functional recovery in stroke survivors is less well established. We explored the impact of BMI on functional recovery and mortality in stroke patients in the China National Stroke Registry (CNSR). ⋯ The stroke obesity paradox can be extended to include functional recovery but should not be interpreted as the fatter the better.
